TWlNE-BALLING MACHINE.

SPECIFICATION forming part of Letters Patent No. 347,116, dated August10, 1886.

Application filed March 11,1885. Serial No. 151E400. (No model.)

To all whom it may concern:

Be it known that 1, ROBERT A. KELLY, a citizen of the UnitedStates,residing at Xenia, in the county of Greene and State of Ohio,have invented certain new and useful Improvements in Balling Machines,ofwhich the following is-a full, clear, and exact description, referencebeing had to the accompanying drawings, forming a part of thisspecifica--- tion.

My invention relates to that class of machines for balling twine, cords,820., by which such twine, cord, &e., are made into balls ready for themarket, and has for its object the simplification of construction, aswell as the increased efficiency, of this class of machines.

The novelty of my invention will be herein set forth, and distinctlypointed out in the claims.

' In the accompanying drawings, Figure 1 is a front elevation of myimproved machine. Fig. 3 is an enlarged detail view,partly in section,of one of the winding-spindles and its connections. Fig. lisa detailview of an attachment to be applied to the machine when it is desired towind cords. Fig. 5 is an enlarged sectional detail of the differentialgearing. Fig. 6 is an elevation of one of the finished balls. is anenlarged elevation, partly in section, of the indicator mechanism.

The same letters of reference are used to in dieate identical parts inall the figures.

A represents any suitable well-braced framework, to which the variousparts of the machine are secured and journaled,and by which they aresupported, and it may consist ofsubstantial end castings united bytie-beams securely bolted thereto. Near thebottom,and at the rear of themachine,issuitably journaled a horizontal shaft, B, upon one outer endof which are secured, side by side, theloose pulley G and tightdriving-pulley D, driven from the line-shafting by a belt, E. Theopposite projecting end of this shaft 13 is likewise provided withadriving-pulley, F. Keyed upon the shaft B within the frame is a beveledpinion, G, meshing with a .similar pinion, H, keyed upon a horizontalshaft, I, at right angles to the shaft B, and which, suitably journaled,extends to the front of the frame and Fig. 7-

projects therefrom to receive a small pulley, J. \Vithin the frame, andkeyed upon the shaft I, is a pulley, K, from which a belt, L, extends upand over two pulleys or (lrums,M, keyed upon the flier-spindles N. Thesespin-' dles, which are hollow to permit the passage of the cord or twinethrough them, are journaled in a boX,.O, open at its bottom, and whichmay be integral with or set into and secured between thesidcs of theframe, and they carry upon their front ends disks P, to which theflier-arms Q are secured. Diametrically opposite the flier-arms andprojecting from the face of the disk are balancing-arms R, as is usualin this class of machines. The twinecarrying spools or bobbins S arehung in a frame, T, supported upon the box 0, and are proyided withpivoted drag or brake arms, U, to prevent the twine being unwound morerapidly than is required.

In the present machine I have made provision for only twowinding-spindles and two fliers; but by increasing the width of themachine as many spindles aud fliers may be employed as desired.

From the bobbins S the twine passes back and, preferably, twice aroundtwo circumfen entially-grooved pulleys,V, each in line with itsrespective spindle N, thence up over and preferably twice around groovedguide-pulleys \V, thence straight through the spindles N and up aroundthe small guide-pulleys ab 0 to the outer endof the flierarms Q. By thuspassing the twine twice around the pulleys V and 'W, or, which 'would bethe same thing, around grooved cylinders or drums in place of pulleys,the twine would be prevented from.

slipping, and a more positive and certain driving of the shaft (1accomplished, and whereby an indicator to show the weight of the twineput.into each set of balls can be connected to either of the shafts ofthe pulleys V or WV, as will be readily understood by reference to Fig.7,where the shaft n of the pulley \V is shown extended beyond theframework, and carries at its end a worn1,'0, that meshes with awormwheel, 1), 'upon the lower end of a vertical shaft, q, whose upperend is provided with a worm, r, that meshes with a gear-wheel, s,withinthe indicator-case L, which has upon its outer side adial with anouter row of equidistant numbers, extending from one to sixteen, toindicate ounces, and to which the ]arger hand, it, points, and also aninner row of equidistant figures, extending from one to twelve, toindicate pounds, and to which the short hand 1" points. The short handis attached to the larger gear-wheel, 10, within the case, which mesheswith the smaller pinion, :r, whereas the long hand is secured to andmoves with the pinion 7 which meshes with the larger pinion, s. The sizeof the gears is made such that the short hand passes over but onedivision of space, while the long hand makes a complete revolution ofthe dial.

The pulleys I) c are suitably pivoted to the flier-arms, and the pulleysa are pivoted in cars proieeting from the disks P, and all of theseguide-pulleys of the twine are so arranged as to guide it properly toprevent its wearing or chafing against any of the parts of the machine.

The pulleys V are keyed upon a shaft, (2', extending across the frameand projecting from one side.

The winding spindles A are constructed and applied in the followingmanner: Hung to the front of the frame by arms 0 is the vibratingspimllecarrier B, occupying a horizontal position across the front ofthe frame, and which I preferably formin the shape of a hollow U -shapedcasting, as shown. The spindles A are inserted through hushed or bosscdapertures in the upper plate of the carrier, and receive upon theirlower ends, after being inserted, keyed worm-wheels f. A. tie-bolt, g.is inserted from the under side through the bottom plate of the carrierand up through the spindle, where it is secured by a head or washer, 71,attached by a tapscrew or otherwise. Journaled through the ends of thecarrier 13 is a shaft, 1', carrying within the carrier wormsj, whichmesh with the wormavheelsj', to cause the revolution of the spimlles asthe twine is being wound on them. In this manner I provide a very secureand simple support for the spindles, wherein the driving parts arehoused and shielded from dust and dirt. The outer end of the shaft i7 isprovided with a grooved pulley, k, either single, as shown, or in theform of a cone to permit the driving cord or belt to be changed toregulate the speed of the shaft 1; during the finishing of the balls.Pivoted, as at Z, to the rear side of the frame, is aforwardly-proiecting arm, m, carrying an adjustable weight, 11, adaptedto slide thereon and be secured at any point desired. The outer end ofthis arm in has a lateral stud or spindle,on whichis pivoted two groovedpulleys, 0 0. A cord or strap, 1), passes down around the pulleyso oandup around a grooved conepulley, r, secured to a sleeve, 8, upon theprojecting end of the shaft (Z. Keyed to the shaft (1, just outside ofthe cone 2-, is a drum, 1, upon two of the armsor spokes of which areloosely fitted beveled gears u it, which mesh with abeveled pinion 0,keyed upon the end of the sleeve 8. Upon the outer eml of the shaft (1is slipped a sleeve, 10, carrying at itsinner end abeveled pinion, 3meshing with the pinions u it, and at its outer end a pulley, O, drivenby a belt, D, from the pulley F. This construction constitutes adifferential gearing, as will be readily understood, the objeet of whichis to cause therapidity with which the twine is fed to govern the speedof revolution of the winding-spindlesin the following manner: The shaft:5 is driven from the conepulley 1' through the medium of the cord orstrap 12, and the cone-pulley is driven by the pulley C through themedium of thedifferential gearing. 1f the gears a were stationary, so asto have a revolution on their axes merely, the speed of the pulley rwould -be uniform with that of the pulley 6; but as the drum i issecured to the shaft 11, so as to revolve therewith by the action of thetwi ne passing through the machine, it is evident that the gears u, inaddition to rotating on their axes, revolve around the gears 3 and '0and in the direction of revolution of the gear r; hence the speed of thegear 12 aml conei' varies with the speed of the drum 1, so that thefaster the drum 1, travels the slower will be the speed of the cone 9,and consequently of the shaft i and winding spindles A. This change inthe speed of revolution of the winding-spindles is rendered necessary tosecure a proper winding of the balls by the gradual increase in the sizeof the balls, and as the balls grow larger they take off the twine morerapidly, and thereby increase the speed of the pulleys V and shaft (1 toeffect the decrease in the speed of the winding-spindles, as beforestated, and thus the machine is remlered automaticin this particular, asin others to be presently explained.

To cause the spindle-carrier with its spindles to so vibrate as topresent the spindles properly to the twine being wound on them, I securean arm, E, to the lower side of the carrier B, which arm carries at itslower inner extremity a roller, F, that bears against a cam-disk, G, ofthe shape shown, which is keyed upon a horizontal shaft, 11, suitablyjournaled in the frame. A belt, 1, passes from the pulley J around apulley,J", fastened, as will be hereinafter explained, upon a shaft,K,whose inner end is provided with a worm, L, meshing with a worm-wheel,M, upon the shaft 11. In this manner motion is communicated from theshaft 13 through the medium of the shaft I, pulleys J and J,and otherparts described, to the shaft 1[, and consequently to the cam, which isshown at its normal position of rest in Fig. 2, just before or at thestarting of the machine,and which makes one complete revolution duringthe complete wi ndingofthe balls upon thespindles, aml then stops topermit the removal of the balls. This cam in its revolution forces outthe S] )ll1(ll0-Cillll(31' B through the medium of the arm 19', and

causes the winding-spindles, whose position of inclination at thestarting of the balls is shown in Fig. 2, to gradually assume a morehorizontal position, and then to return again to their first position asthe winding of the balls is completed. From this vibration of thespindle-carrier B will be seen the necessity for having the weighted armm and pulleys o, for as the carrier travels up or down the pulleys 0rise and fall, and at all times maintain the proper tension of thedriving-strap 1).

To cause the machine to stop automatically when the balls are finishedand the cam has made an entire revolution, I employ the followingmechanism: Two horizontal rods, N O, extend across the machine and haveslid ing bearings in uprights I suitably secured to the frame-work.These rods, which are preferably round in section, are held from turningbya clam p-brace, a, Fig. 1. The rod N carries at its projecting end anadjustable perforated head, It, from which the beltshipper rod S,embracing the belt E, extends and is secured by a set-screw, b. Coiledaround the rod N is a spring, 0, which bears at one end against one ofthe uprights, I and at the other against a shoulder or swell upon therod N. A lever, U,pivoted, as at d, at the back of the frame, extendsforward tothe front of the machine, and is provided with anoperating-handle, c. This lever U is con nected by a slot and pin to therod N, so that by taking hold of the handle 6 the rod can be drawn backto compress the spring 0 and to cause the belt E to be shipped to thedrivingpulley. To hold it when thus shifted the for- .ward end of thelever U rests upon the top of a standard, V, at the front of themachine,

provided with stop'shoulders f, to one of which is pivoted a latch, g,that catches over and engagessthe lever U when the belt has been shiftedto the fight pulley. A stud or pin, h, is so arranged upon the cam Gthat when said caln has just about completed its revolution the pin itcomes in contact with the projecting end of and lifts the latch therebyfreeing the lever U and the spring 0, which, recoiling, forces out therods N O and consequently the shipper, thereby throwing the belt ontothe loose pulley and stopping the machine. To restart the machine, itisonly necessary to draw back the lever U until it is engaged by the'latch g, whereupon the belt will be shifted to the tight pulley, asbefore described.

Ifit is desired to stop the machine-lat any time before the completionof the winding of the balls, it is only necessary to trip the latch gand the spring 0 will cause the belt to be shifted to the loose pulley,and to do this the more readily I provide an operating-handle, i, whichprojects forward from the rear end of the latch g, as shown.

The arrows in the different figures will show the direction ofrevolution of the various parts, .and it will be understood that the rod0 is only employed to prevent the turning of the rod N through themedium of the clampbraee a.

\Vhen it is desired to ball cord, I provide an attachment to themachine, which is shown in Fig. 4, which can be readily put onto ortaken off the machine, as the case requires. It consists of any suitableframe, j, carrying grooved rollers 7t" and rope-covered stretching andrubbing rollers Z, which are rex'olved in directions opposite to theline of travel of the cord by a belt, an, arranged as shown, and drivenfrom a pulley (not 'shown) upon the shaft B. The cord leaving thepulleys l, by which it is stretched and its projecting fibers removed,passes over a small grooved guide-pulley, m, and thence around thepulley V on its way to the winding-spindles.

Having thus fully described my invention, I claim- 1.
